Updates greenlet from 3.5.0 to 3.5.1

Changelog

Sourced from greenlet's changelog.

3.5.1 (2026-05-20)

• Add preliminary support for Python 3.15b1. This has not been reviewed by CPython core developers, but all tests pass. Binary wheels of this version won't work on earlier Python 3.15 builds and may not work on later 3.15 builds.
• Fix the discrepancy in the way the two getcurrent APIs behave during greenlet teardown. One API (the C API used by, e.g., gevent) raised a RuntimeError; the other (the Python greenlet.getcurrent API) returned None. This second way is incompatible with greenlet's type annotations, so greenlet.getcurrent now raises a RuntimeError as well.
